Yep, the sky lab rocks. I think if Corel was wise, they'd hire Eric Wenger to redesign Bryce for the Bryce 5 release. Leave the stuff alone that's already good, tweak the render engine a bit and add some modeling capabilities. It couldn't be that hard to create a basic new window plug in that would at least give spline, extrude and lathe modeling capabilities.

Talent is God's gift to you. Using it is your gift to God.
